To all'whom if concern:

Be itfknbwn thatl, GEORGE-R. '-DEAN, a citizen ofthe United States,residing at Chi' cago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Pipes, of which thefollowing is a specification.

My invention relates to pipes, and has for its object to provide meansequivalent to a trap for the purpose of givin an unobstructed passage tothe VSimo e and air through the pipe stem while at the same timepreventing the entry of li uids into the stem. Seme y of the forms inwhich I contemplate applying my invention are found in the ac.-co'mpanying drawings, wherein- Figure 1 is a side view with the lupperpart of the Istein shown in cross section; Fig. 2, an

enlarged'view of said cross section; Fig. 3,' a section online 3-3 ofFig. 2; Fig. 4, a detail of the plug of Figs. 2, 3 and 6. Fig. 5, asection 'similar to Fig. 2 of a iiiodiiication; Fi v6,. a sectionsimilarlto Fig. 2.of

another modieation Fig. 7, asimilar section of alike imodiiication; Fig.8, a view of the plu of LFig. 5, and Fig. 9, a view of the plug of Fig.7.

Like arts are indicated by the same number'in a l the figures.

I'isthe bowl of the pipe, 2 the stem and 3 the mouthpiece. The smokepassage through the stem is indicated at 4. The mouth iece, referring toFig. 2, is enlarged and as 'a cavi-ty 5 into which is screwed the plii6*, the upper end of which is cut away 0n bot sides so as to leave thediaphragm 7. When the plug is screwed into the position shown in Fig. 2this diaphragm, being of the same di ameter as the plug, fills all theparts of the cavity 5, leaving va passageway over the top of saiddiaphragm. phragm, of course, are -screw threaded-like the body of thelug so that when the plug is screwed down, tlie vscrew threads on theedges take into the screw on the lower part of the cavity and if theprocess be continued until the top. of the diaphragm is level with thelower part of the passage 4, the latter will be free so that the passagecan be mechanically cleared. The threads in the upper part of the cavityare preferably cut away as shown in Fig. 2. When the parts are in theposition shown in Fig. 2, the smoke passage is left free and ofsubstantially `uniform cross section throughout, but the diaphragmoperates as a trap to prevent the entry of liquids into the pipe stemthe' mouth side.

The edges of the dia? 'iead of the plug 6,

4 is cut clear across l l 'In Fig. 5, the mouth piece' is differentlyshaped to .suit the convenience of different Snickers. The smokepassage, as before, consists of .the two channels 4, 4,\but the plug isdifferently shaped the new position. It consists of the body 8 but inthis case the diaphragm 9 is differently constituted, theparts being cutout so as to leavean opening 10 over or throu h the top thereof, topermit the passage'of t e smoke. The trapping effect is the same asbefore.

In Fig, 6, the structure is very much like that of Fig. 2.

In Fig. 7, the plug 11 is inserted from the to i and the diaphragm 12extends up from a ottoni piece 13 so as to leave the usual passagewayover or through the top of the ditphragiiil at I4. f

n Fig. 6,' the forward part of the passage the face of the mouth carriedaround .tothe as shown, so that the trapping eiect is still produced andthe liquid does not run into the pipe or stay in the mouth piece.

It will be understood, of course, that my drawing is to' be taken asdiagrammatic and sim l ly illustrative of my general idea, while ieeeand the slot is 'at yt e same time some of the specific forms in which Ihave intended to utilize the invento indicate sim .smoke and air, but inall tion are illustrated.

I have used the term mouth piece as a descriptive' term though',- ofcourse, it is in efect nothin but that end of vthe stem which is heldinthe mouth. .It may be and often is made of special size or shape. Inthe claims I use theterm in its broad sense ly' that end of the stemwhich'is put in t e mouth.

, The use and operation of my invention will.. be readily understood.The `moutli piece and stem should be properly positioned so as to suitthe taste of various smokers. For that purpose, therefore, there shouldbe various ty es. The essential quality is that there shou d be a traplike structure at the up` perpart of the stem adapted to permit the freepassage of smoke, air and the like, but to prevent the entry of liquidsinto the pipe stem. The diaphragm-in any or all of the positions shownpresents no obstacle to the passage of positions, when the pipe isproperly hung in t e mouth the eii'eet is to trap t e liquid.

The smoke and air passa e in the pipe of my invention is downwardlyturned at its A mouth piece having outer end as shownier example, inFig. o, and the smoke descending, im ingesv on a laterallyextendedsurface whic scatters it -in the mouth. Injother words,-thesmoke mouth Iieee connected with t e passageway in the's em, and aremovable plug adapted to enter theenlar ed aperture ,screw threaded'-at one end an carrying a flattened dia-V phragm at the other.

2. A pipe comprising a bowl, a stem', a mouth piece, an aperture in saidmouth piece connected with the passage in the stem, a removable screwthreaded plug for said aperture c carrying a. diaphragm to form acircuitous air and smoke assage, and a liquid trap screw threaded on itsedges.

y3. A pipe comprising a bowl, a stem and a a circuitous smoke and 'ofwhich is downair passage, the outer end wardly'turned, and a deflectingsurface bef neath the end of such passage to scatter the smoke.

4. A pipe lcomprising a bowl, a stem and a mouth p'iece, a diaphragm inthe mouth piece so as to form a circuitous smoke and air passage, theouter end of which is downwardly turned, and a deliee'tingy surfacebeneath the end of such passage to scatter the smoke.

` 5. A pipe comprising a bowl, a stem and a mouth piece liaving'acircutous smoke and airv passage, the outer end of which is downwardlyturned, and a deilecting surface beneath the end of such ,passa e toscatter the smoke, said deflecting su ace formed by slotting the mouthpiece.

' 6. A pipecomprismga bowl, a stem and a mouth piece, a diaphragm in themouth piece y so as to form a circuitous smoke and air passage, thevouter end of which is downwardly turned, and a delecting surface beneaththe end of such passage to scatter the smoke, said 'deflecting surfaceformed byslotting the' mouth piece. p
